SPECIFICATION forming part of Letters Patent No. 482,983, datedSeptember 20, 1892.

Application filed May 9, 1892. Serial No. 432.823. (No model.)

To all whom it may concern:

Be it known that I, EDWIN S. PIPER, of Bristol, in the county ofHartford and State of Connecticut, have invented a new Improvement inBells; and I do hereby declare the following, when taken in connectionwith accompanying drawings and the letters of reference marked thereon,to be a full, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and represent, in

Figure 1, a view in side elevation of a bell constructed in accordancewith my invention and adapted to be used as a call-bell; Fig. 2, a viewof the bell in vertical central section; Fig. 3, a plan view of the hellwith the gong removed and the movement-frame shown in transversesection.

My invention relates to an improvement in call and door bells, and hasparticular relation to the hammer and to the mechanism for operating thesame, the object of the invention being to produce a simple, durable,convenient, and effective device.

With these ends in view my invention consists in a bell having certaindetails of construction and combinations of parts, as will behereinafter described, and pointed out in the claims.

As herein shown, the gong A, which is of ordinary form, is provided witha central internally-threaded hub A, adapting it to be secured to anexternally-threaded post B, which is mounted upon the upper portion of abridge-like movement-frame C, adapted to be secured within the circularopening of the bell-support D, which may also be of any approvedconstruction. The said post B is provided with a longitudinal bore B,which receives a push-rod E, furnished at its upper end with a button Eand having its lower end connected with a chain F, wound upon ahorizontal driving-shaft G, having its ends journaled in the said frameC, the said chain being wound once or more around said shaft andattached thereto. The said push-rod E forms a manual by which the bellis primarily actuated. If desired, the chain may be replaced by a cordof fiber or gut. A tube H,

secured to the movement-frame C, on the inside thereof, forms in effecta continuation of mounted on a horizontal driven shaft K, ex

tending parallel with the driving-shaft G before mentioned and alsohaving its ends journaled in the movement-frame C. A coiled spring L,attached to the driving-shaft G at one end and to the movement-frame Cat the other end, is arranged so as to rotate the said shaft in thereverse direction from which it is rotated by the chain when thepush-rod is depressed, the depression of the push-rod rotating the saidshaft and placing the spring under tension, so that when the push-rod isrelieved of pressure the spring uncoils and reversely rotates the shaftand drives the driven shaft. The said driven shaft is also provided witha collar M, carrying a plate M, which is furnished, as herein shown,with four pins m, arranged in two pairs, respectively receiving the endsof two bowed springs N, located opposite each other and each carrying adisk-shaped striker O. Each of the said strikers is constructed with anarrow diametrical slot 0 to receive its spring, to which it is solderedor otherwise attached. The said collar M and plate M form, as it were, ahub for the connection of the spring-mounted bellhammers with thedriving-shaft, each striker and its spring forming a spring-mountedbell-hammer. I would have it understood, however, that I do not limitmyself to constructin g and mounting the strikers as shown, so long asthey are carried by springs arranged to permit them to be thrown outwardby centrifugal force as the driving-shaft is rotated. In order to permitthe said hammers to engage with the edge of the bell, the upper edge ofthe bell-support D is slotted for that purpose, as at D.

It will be readily understood that my improved bell may be adapted foruse as a doorbell by moditications in the mountings and proportions ofthe mechanism, which will be too apparent to any one familiar with thesubject to require illustration. It will also be equally apparent thatit may be used with some modifications of form and proportion as abicycle-bell, in which adaptation the push-rod might be replaced byalever having its outer end adapted to be manually engaged and its innerend connected with the chain wound on the driving-shaft. I wouldtherefore have it understood that I do not limit myself to the exactconstruction herein shown and described, but hold myself at liberty tomake such changes and alterations as fairly fall within the spirit andscope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a bell, the combination, with the base and gong thereof, of atrain, a manual connected with the same for actuating it in onedirection, a spring for actuating the train reversely when the saidmanual is released, and one or more spring-mounted rotary bell-hanr merswhich are thrown outward to strike the bell when the train is actuatedand each consisting of a spring connected with a rotary member of thetrain and having the striker attached to its outer portion,substantially as described.

2. In a bell, the combination, with the base and gong thereof, of atrain, a manual connected with the same for actuating it in onedirection, a spring for actuating the train reversely when the saidmanual is released, and one or more rotary spring-mounted bell-hammers,each consisting of astriker and a bowed spring the ends of which areconnected with a rotating member of the train, substantially asdescribed.

3. In a bell, the combination, with the base and gong thereof, of atrain comprising a driving and a driven shaft, a wheel and a coiledspring on the former, a push-rod adapted at its outer end for manualengagement, a chain wound one or more turns on the driving-shaft andconnected thereto and to the inner end of the push-rod, a pinion on thedriven shaft meshed into by the said wheel, a hub on the driving-shaft,and one or more spring-mounted bell-hammers connected with the said huband thrown outward for engagement with the bell when the driven shaft isrotated with sufficient speed, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
